@Dave un extrait mis à jour de http://www.php.net/manual/en/function.strpos.php#107351
function strposa($haystack, $needles=array(), $offset=0) {
$chr = array();
foreach($needles as $needle) {
$res = strpos($haystack, $needle, $offset);
if ($res !== false) $chr[$needle] = $res;
}
if(empty($chr)) return false;
return min($chr);
}
Comment utiliser:
$string = 'Whis string contains word "cheese" and "tea".';
$array = array('burger', 'melon', 'cheese', 'milk');
if (strposa($string, $array, 1)) {
echo 'true';
} else {
echo 'false';
}
renverra true
, à cause de array
"cheese"
.
Mise à jour : Code amélioré avec arrêt lorsque la première des aiguilles est trouvée :
function strposa($haystack, $needle, $offset=0) {
if(!is_array($needle)) $needle = array($needle);
foreach($needle as $query) {
if(strpos($haystack, $query, $offset) !== false) return true; // stop on first true result
}
return false;
}
$string = 'Whis string contains word "cheese" and "tea".';
$array = array('burger', 'melon', 'cheese', 'milk');
var_dump(strposa($string, $array)); // will return true, since "cheese" has been found
